IVIILK COOLING AND AERATI-NG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 620,671, dated March 7, 1899.

Application filed March l5, 1898.

To @ZZ whom t may concern:

Be it known that I, VILLIAM JOHN RICK- ENBACHER, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented a new and useful Milk Cooling and Aerating Apparatus, of which the following is a specication.

My invention relates to milk cooling and aerating devices, and has for its object to provide a simple, compact, and efficient device adapted to be supported by an ordinary milk-shipping can and having means for aerating milk prior to the cooling thereof, and subsequently cooling the same to the proper temperature for shipment or immediate use.

Further objects and advantages of thisinvention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side View of a cooling and aerating apparatus constructed in accordance with my invention applied in the operative position to a milk-can. Fig. 2 is a vertical central section of the same. Fig. 3 is a ,detail view of the conical retainer detached. l

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

The device embodying my invention consists of a body portion 1, forming a cooler and designed to be supported by the mouth of' a milk-shipping can, such as that indicated in part at 2, and a distributing-receptacle 3, supported above the receiving-surface of the cooler and designed to receive milk preparatory to the operation of aerating and cooling. The receptacle or tank 3 is provided in its bottom with a series of separated perforations 4, designed to discharge themilk in fine streams and drop the same upon the coolingsurface of the body portion 1, the receptacle being supported by standards 5, secured at their lower ends to the body portion.

The cooling device is of double-walled construction, having an inverted conical inner or upper Wall 6, forming a receiving-surface and provided with a peripheral flange 7 to prevent splashing of the milk deposited thereon in the small streams falling from the bottom of Serial No. 673,950. (No model.)

the distributing-receptacle, said receivingsurface being annularly corrugated, as indicated at 8, to detain the milk in its course to the central depressed outlet-tube 9. The outer wall 10 constitutes a shell around the receiving funnel or hopper, (formed by the inner or upper wall 6,) said shell being of inverted conical construction to it within the mouth of the above-mentioned shipping or other can 2. Communicating with the coolingchamber formed between the inner and outer walls of the body portion of the cooler is an inletspout 1l, preferably provided with a hinged lid 12 and an overflow-vent 13, said coolingchamber being adapted for the reception of ice or other cooling agent or being adapted to be continuously supplied by a stream of running water, as from a tank. (Not shown.)

.The outlet-tube 9, which leads from the milk-receiving surface of the cooler, extends through without communication with the cooling-chamber, and is so constructed as to provide for the attachment thereto of a textile strainer 14, held in place by an encirclingband 15, and adjustably located in the tube is a conical retainer 16, of which the peripher-y at its base or larger end fits snugly in the bore of the tube to adapt it to be held frictionally in any desired position. At its apex this retaining-cone is provided With an outletopening 17, whereby milk after it has flowed down the Walls of the tube above the retainer and has accumulated around the retainer to a sufficient depth to reach the outlet-opening will pass through the cone to the textile strainer. The annular pocket between the conical retainer and the Wall of the tube forms a receptacle for the accumulation of sediment,

which may be carried by the milk into the cooler or may be deposited in the form of dust upon the surface 6.

In order that all of the contents of the initial tank or receptacle may escape through the perforations 4, I preferably depress the bottom of the said receptacle 3 toward its edge by forming a coned floor. (Indicated in Fig. 2.)

As the milk flows in small streams from the perforations of the receptacle 3 and falls upon the cooling-surface 6, which is located at a considerable distance, as eighteen inches, from the bottom of the receptacle, itis aerated while yet warm, as it is well known that milk after having been cooled cannot be properly aerated and deodorized. The milk falling in streams upon the surface 6 iows inwardly over the impeding or detaining corrugations to the central outlet-tube and thence follows the inner wall of the tube to the annular' pocket between the same and the conical retainer, the same throughout its passage being i exposed to the cooling action of the contents of the chamber formed between the inner wall 6 and the outer Wall l0.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim isl. A milk cooling and aerating apparatus, having an eXteriorly-conical cooler, adapted to be seated in the mouth of a milk-receptacle, and provided with inner and outer spaced walls forming an intervening cooling-chamber, the inner wall being centrally depressed, an outlet-tube in communication with the depression formed in the innerwall, and an initial tank or receptacle arranged above and supported by the cooler and provided with an annular series of spaced perforations-for discharging' its contents upon the inner wall of the cooler contiguous to its outer edge, substantially as specied.

2. A cooling and aerating apparatus, having a double-walled cooler forming an intervening chamber for a cooling agent, and having an inner or upper Wall of inverted conical construction provided with annular corrugations, an outlet-tube extending downwardly from the center of the inner or upper wall, and an initial tank or receptacle arranged above the vcooler 'and provided with spaced perforat-ions for discharging milk in small streams upon the cooling-surface, substantially as specified.

3. A milk-cooler and aerating apparatus, -comprising a cooler having an upper inverted conical cooling-surface, a discharge-tube eX- tending downwardly from the center of said cooling surface, and a l'surrounding wall spaced from said cooling-surface to form an intervening chamber for a cooling agent with which communicate inlet and overflow passages, a distributing-tank located above the cooling-surface and having a perforated bottom for discharging milk in streams upon said surface, and a conical retainer located in the discharge-tube and provided at its apex with an outletopening, substantially as specified.

4t. A milk cooling and aerating apparatus, comprising a cooler having an inverted conical cooling-surface and a surrounding spaced shell forming an intervening cooling-chainber, au inlet-spout and an overfiow-vent communicating with the cooling-chamber, the inlet-spout being provided with a movable cover, a central discharge-tube depending from the center of the cooling-surface, standards rising from the periphery of the cooler, and a distributing-tank supported by said standards and provided with a conical bottom having discharge-perforations contignous to its depressed periphery, for depositing milk in small streams upon the lcoolingsurface, substantially as speciiied.

5. A cooling and aerating apparatus, having a cooler comprising an inverted conical cooling-surface forming the inner or upper wall of a chamber for a cooling agent, and having a central depending discharge-tube, means for distributing milk upon the coolingsurface, and a conical retainer peripherally tted'for vertical adjustment in the dischargetube and provided at its apex with an outletopening, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnessesA WILLIAM J. RIcKENBAcIIER.
